Did you try doing a dd(1) if some blocks of zeros to the drive before doing the fdisk. On some older FreeBSD - don't remember which - I had trouble with some brands of SCSI disks and writing some zeros to it seemed to make it work. I don't know why or even why I first tried it. But it is simple enough to be worth giving it a try to see if anything improves. dd if=/devf/zero of=/dev/da5 bs=512 count=1024 ////jerry > > Simon > > > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
